A powerful 7.6-magnitude earthquake struck southwest Mexico, causing residents in the capital several hundred miles away to rush out onto the streets but no immediate reports of serious damage. The quake struck near the tourist resort of Acapulco, just after midday some 25 km northeast of the town of Ometepec, the US Geological Survey said. Earlier it had estimated the magnitude at 7.9, before downgrading it to 7.6. AFP PHOTO/RONALDO SCHEMIDT
